The lenses on eclipse glasses expire after three years, meaning they're not safe to use when the next solar eclipse moves through eastern Canada, the central United States, and part of Mexico in 2024.

The total solar eclipse is over, leaving many people wondering what to do with their numerous pairs of eclipse glasses left over from the event. It turns out that a new standard for eclipse viewers, called ISO 12312-2, was adopted in 2015, and the new standard means the viewers are durable.

If you have a pair from a reputable vendor and plan to reuse them, make sure the lenses aren't scratched or damaged over the next seven years.

The organization is collecting the glasses for distribution to schools in South America and Asia, which are expecting an eclipse in 2019. One possible idea is to frame the solar eclipse glasses alongside an image of the phenomenon. By donating your eclipse glasses, you'll be donating a chance to appreciate the world a little more. If all of them were just trashed, that's a lot of unnecessary waste going to the landfills. "With branches in Cheyenne and Casper, we were fortunate to be able experience the solar eclipse firsthand".

For months and months, countless eclipse-viewing hopefuls have been buying up special protective shades so that they could gaze skyward on August 21st and enjoy the lovely celestial event in all its glory. They'll have a collection box right outside their building, where you can drop them off during normal business hours from 9 a.m. until 5 p.m., Monday through Friday at 11002 Kingston Pike, Suite 204, Knoxville, TN 37934.
